Available in PDF, EPUB and Kindle. Book excerpt: Zebra mussels, one of the most recent non-indigenous species to invade the Great Lakes, achieves extraordinary population densities in the lower lakes. They draw in water and filter a broad range of suspended particles, and have the potential to alter contaminant cycling in invaded lakes. They are also a conduit for contaminants and energy to higher trophic levels by serving as prey for fish and waterfowl. This study assesses the suitability of the zebra mussel as an organic contaminant biomonitor in the lower Great Lakes and also addresses its importance to waterfowl diets and body burdens or organocontaminants. It presents results of elimination rate determinations for polychlorinated biphenyl (PCB) congeners and contaminant levels in mussels from vaiours sites in Lake Erie and Lake St. Clair; results of experiments to determine the contribution of food to zebra mussel PCB accumulation; and statistical analyses of contaminant data for six species of ducks, examining differences in contaminant levels between those that consumed zebra mussels and those that did not.
